CJC-1295 — How It Works

CJC-1295 docks onto the GHRH receptor in your pituitary gland — the same receptor your brain's natural growth hormone signal uses. This tells the pituitary to produce and release growth hormone. What makes CJC-1295 different from the natural signal is its DAC modification, which lets it attach to albumin (a blood protein) and hitch a ride through your bloodstream for days instead of minutes. This keeps growth hormone levels elevated in a sustained, natural-feeling way rather than a sharp spike.

Ipamorelin — How It Works

Ipamorelin mimics ghrelin — the hormone your stomach releases when you are hungry, which also signals the pituitary to release growth hormone. By binding to the ghrelin receptor in the pituitary, Ipamorelin triggers a clean GH pulse. Unlike older growth hormone peptides (like GHRP-6), it is highly selective, meaning it only activates the growth hormone pathway and leaves cortisol and prolactin largely untouched. This selectivity is what makes it so popular for long-term use.
